Answer: 19 /4 or 4 3/4
Step-by-step explanation:
Turn 67/8 into a improper fraction, which is 55/8
Next, also convert 21/8 into an improper fraction, which is 17/8
Next, subtract 17/8 from 55/8 and you should get 38/8
Last, simplify 38/8 to do so divide 38/8 by 4/4 and you should get 19/4 and if you want it's optional to turn it into a mixed number.
The estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.
To find the difference of two fractions means that subtract one from the other.
Thus:
Difference between 6 7/8 and 2 1/8 = 6 7/8 - 2 1/8
Change the mixed fraction to improper fractions
55/8 - 17/8
= (55 - 170/8
= 38/8 = 19/4
= 4 3/4 = 4.75 ≈ 5.
Therefore, the estimate of the difference between the two fractions is: 4 3/4 = 4.75 ≈ 5.
